Early Applications in the Message-Passing Interface (Mpi)

We describe a number of early e orts to make use of the Message Passing Interface (MPI) standard in applications, based on an informal survey conducted in May-June, 1994. Rather than a de nitive statement of all MPI development work, this paper addresses initial successes, progress, and impressions that application developers have with MPI, according to the responses received. We summarize the important aspects of each survey response, and draw conclusions about the spread of MPI into applications. An understanding of message-passing, and access to the MPI standard are prerequisites for appreciating this paper. Some background material is provided to ease this requirement. Skjellum, et al.
